3 Claims.

My invention has reference to an attachment for plows of the framelesstype, for readily elevating the plow to a substantial height from theground in which it is working, or under other conditions, and therebyadding facility and convenience to the operation and care of such plows.

The objects of said invention, generally stated, are: i

To provide in a frameless plow, a device which permits the entire plow,through a simple single manipulation of the mechanism of said device, tobe elevated as required, and then by a release of said mechanism to bebrought back into plowing position, the same being accomplished whilethe plow is under propelling power;

To afford a device, having these characteristics, which may be attachedto any frameless plow, of ordinary construction;

To supply a device which is particularly effective in the type offrameless plow designed to be pulled by a horse-drawn plow sulky or amotor vehicle; and,

To make available, a device of this kind which is simple in constructionand easy to operate.

In the accompanying drawing Figure 1 is a side elevation of a framelessplow with said device attached, the plow being indicated as in operativeposition for plowing, and carrying a clevis.

Fig. 2 is a side elevation of the same, the beam of the plow, however,being broken away and the plow shown as elevated by said device.

Fig. 3 is a horizontal section, drawn on the line 3-3, of Fig. 2, .beingparticularly designed to show the swinging connection of a shoe of thedevice with said plow.

Fig. 4 is a rear elevation of said shoe and a link connecting the shoewith the actuating lever of the device, the View also showing theswinging e0 connections of the link with said shoe and lever.

Fig. 5 is a cross section, drawn on the line 5--5, of Fig. 1,particularly illustrating an angle iron support bolted to the beam ofthe plow and adapted to support said lever, a stop for the lever beingalso indicated.

Referring more particularly to the drawing, 1 denotes the beam of aframeless plow, carrying at one end a clevis 2, and at its other end anintegral and curved standard 3, said standard 50 having mounted thereto,a share 4, a moldbo-ard 5, and a landslide 6. The parts just enumerated,as is obvious, present the usual construction to be found in framelessplows, and well known in the art.

Said device, designed primarily to be constructed of metallic material,comprises a support 10, made preferably of angle iron, and is adapted toextend longitudinally of said beam for a portion of the length of thebeam and slightly beyond the rear portion thereof, as indicated inFig. 1. An integral stop 11, for the actuating lever heretofore referredto, is formed in said support by making a lengthwise cut through one endof the support and then bending the lower section thus cut so that itextends laterally from the side of the support, as shown in Fig. 2. Saidsupport is secured to said beam by bolts 12 extending through thesupport and beam.

The actuating lever 13, is provided with a handle l4 offset to affordknuckle space between the 0 handle and said beam, and is pivotallyconnected with the support 10, as at 15, the stop 11 serving to limitthe downward swing of the lever 13. When the plow is supported on asuitable surface, such as a floor or the ground, the contact of the shoetherewith will serve to hold the lever 13 in a horizontal positionagainst the stop 11, and during a plowing operation the slight pressureof said shoe against the bottom of the furrow will subserve the samepurpose.

A shoe, generally designated as 16, is provided with an approximatelyflat and elongated body portion 17, slightly curving upwardly at eachend, and reduced in width at its inner end. The inner extremity of saidshoe is bent on itself, as at 18, to afford a portion, circular in-crosssection, which imparts to the shoe a swinging connection with certainelements of the plow. These elements comprise a block 20 secured to thelandslide 6 by bolts 21 countersunk in the exterior surface of 99 saidlandslide, said bolts also serving to hold in place a support 22. Also,a support 23 is secured to the share by bolts 24, said support beinglocated oppositely of the support 22, and having its outwardly disposedend bent so as to bring the same into spaced parallel relation with saidsupport 22. The free ends of the supports 22 and 23 are apertured toreceive a rod 25, which rod, when in place, is mounted in the portion 18of the shoe and is fixedly secured in said supports. As it may be notedin Fig. 3, said rod and the portion 18 provide a relatively wide andstrong swinging connection for the shoe with the plow.

The shoe 16 and said lever 13 are connected by a vertically extendinglink, denoted generally as 30. Said link comprises a body member 31,which may be made of angle iron, the same being apertured at each end,and pivotally connected at its upper end with the lever 13,as at32. 33designates a supporting and bracing member bolted to the body member 31,it being apertured at its lower end, and is designed to provide, inconnection with said body member and certain elements mounted on saidshoe, a wide swinging connection for said link with the shoe. Theelements last referred to comprise a support 34 having upstanding andapertured end portions, said support being secured to the shoe by bolts35 countersunk in the exterior surface of said shoe, and a bolt 36extending through the end portions of said support, designed, when inplace, to be fixedly secured therein. As it may be observed particularlyin Fig. 4, the lower ends of said link swingingly engage the bolt 36.

In operating the device, it is assumed that said plow, equipped withthis attachment as shown and described, has been suitably connected upwith a horse-drawn plow sulky, for instance, and the parts are in thenormal positions shown in Fig. 1. The assembly is now in position forplowing, the shoe 16, when plowing, riding along on the ground andserving as a rear stabilizing element. When it is desired to elevate theplow for the purposes heretofore adverted to, or for any purpose, thelever 13 is raised by the operator, and, as is evident, the forceexerted thereby is communicated, through the link 30, to the shoe l6contacting with the ground. Said shoe is then raised along the majorportion of its length and serves to elevate the plow clear of the groundand to a sub stantial height from the level it first occupied. Thisresult may be readily accomplished while the plow is in motion, thehandle 14 of the lever 13, located as it is adjacent the front end ofthe beam, being within convenient reach of the driver of said sulky.

As it may be noted in Fig. 2, when the plow is thus elevated, the rearend of the shoe contacts with the ground level and obviously will thenfunction to a certain extent as a stabilizer. Under this construction,the plow remains elevated as long as the operator holds the lever 13 inits raised position. When it is desired to return the plow to its normalposition, this is effected simply by lowering the lever 13 into contactwith the stop 11, as shown in Fig. 1, when, as is evident, the otherparts of the attachment and the plow, which were initially set inmotion, will assume their normal positions.

A plow, having a single cultivating unit, has been shown and describedin connection with this attachment, as it is deemed that the same willsufficiently indicate the construction and mode of operation of myinvention. In plows of the frameless type, it is common to provide aplurality of cultivating units connected together. This device, as willbe obvious to those skilled in the art, may be utilized in suchconstruction, and wherein a single assembly, as shown and described,will serve to handle a plurality of such units.

In plowing, it is often desirable to raise the plowing instrumentalityon turns of 45 degrees or less, and this attachment renders such actionsimple and effective, not only on account of the facility with which itmay be applied, but the resistance of the machine to the ground in whichit is employed will be lessened on a turn, such as referred to, as theplow will be then turned on the rear end of said shoe instead of thebottom of the plow.

Further, as it may be noted, the device serves to elevate the plow clearof the ground or the level on which it may be standing. Ihis isdesirable not only when working the plow, but in removing the share orother of the cultivating elements of the plow, or in making repairs oradjustments thereto.

While this attachment facilitates the use of small plows, its usefulnessin this respect increases when employing larger plows of the type towhich it is adapted, as obviously the latter are more wieldy to handle.

For the purpose of illustrating my invention, I have shown in theaccompanying drawing a typical embodiment thereof, but I may, however,provide other arrangements and constructions for carrying out theinvention, outside of those heretofore referred to, without departingfrom the spirit or scope of the invention as defined by the appendedclaims.
